During our conversation, I also learned that he lived in downtown Orlando within a few blocks of a SunRail stop. This doctor-in-training, whose hospital has its own station, is about the perfect candidate to ride SunRail, and he didn't know it existed.

As the commuter rail service officially opens May 1, there are still residents of Central Florida that have no idea what SunRail is, how it works, where it goes and how much it cost to ride.

In the past few weeks, the Orlando Sentinel has been rolling out blogs and maps and stories highlighting arrival of SunRail in hopes of informing the region.
